"Do you think marriage will be devalued if gay people are allowed to marry?"
No, I don't. Gay people atm are unable to show their committment to each other, if that's what they want, so there should be some mechanism for that.

"Do you feel that the relative ease of divorce is a good thing or not? Why?"
Is divorce that easy? I don't really have enough knowledge of it to make a judgement. Although,I know soemone who left her dh less than a year after their wedding - I think there should be a law that you have to return all wedding pressies if your marriage doesn't last at least two years! Maybe marriage should be harder to to do, not divorce.

"Do you think people have a rose-tinted view of marriage and are less prepared to work at it these days?"
Yes, see my comment above. I think people split up for more trivial sounding reasons nowadays. People also don't seem to regard themselves as two halves of a whole in marriage eg keeping money in separate acc's, divvying up bills etc. I think the instant gratification and disposable society we live in has changed expectations.

"If we went back to the days when divorce was difficult, what do you think would be the effect on women's lives, if any?"
I wouldn't like to see divorce made more diffucult, tbh.

"And lastly, he is vehement that studies exist showing that children from families where the parents have a marriage certificate are statistically more likely to do better than children from families where there are two unmarried parents. Have you ever heard this? I find it hard to believe."
Yes, I've read this type of study but I don't recall the basis, unless it's that unmarrieds are more likely to split up and therefore children are brought up in more poverty?

One thing that I find a bit sad about most of my nieces not being married is that I've either never met the fathers of their babies or there's been no chance to 'officially' welcome the dads into our family. But that's just me being sentimental, I guess.
